Description

An outdoor louver awning with independently flippable opening and closing louvers and retractable stacking Technical Field

[0001] The present invention relates to the technical field of outdoor products, and in particular to an outdoor louvered tent with independently flippable, openable, and foldable louvers. Background Art

[0002] To meet the current demand for outdoor awnings, a variety of awnings have emerged on the market, such as fixed-roof sunrooms. These cannot be retracted, limiting their use. Another type of sunroom with a single function is the traditional fixed flip-up louver sunroom, which only allows the louvers to flip, not retract. This structure fails to meet the customer's need for direct sunlight and unobstructed access to nature.

[0003] For example, publication number CN110886533B discloses a louvered tent comprising a tent frame and a louver assembly. The tent frame comprises at least two louvered beams and at least two columns. The columns are provided with a transmission mechanism, and the louvered beams are provided with a flipping device. The transmission mechanism controls the flipping device via a linkage, thereby flipping the louver assembly. While a chain drive is used to achieve the flipping mechanism of the louvers, it cannot achieve a partially open structure.

[0004] To this end, a retractable louver canopy is provided in the announcement number CN212295260U, which belongs to the technical field of awnings. It solves the problems of existing louver canopies that can only satisfy the function of opening and closing by driving the louver plates to rotate with the transmission parts, and the effect is single and the lighting is not ideal. The utility model includes a canopy, a canopy mounting frame and a canopy opening and closing mechanism. The canopy includes a plurality of louver covers. The canopy opening and closing mechanism is arranged on the canopy mounting frame, which can drive the louver covers to move back and forth and realize flipping and opening and closing during the back and forth movement. When the plurality of louver covers move back and forth and rotate to a closed state, the adjacent two louver covers are first docked together. The retractable louver canopy of the utility model is not only sturdy, but also the canopy as a whole can be retracted and retracted back and forth. During the retraction process, the plurality of louver plates of the canopy can also be rotated and buckled to close to realize the function of sunshade and rain shelter. The retractable louver canopy is easy to use and can greatly improve the lighting effect to meet the different needs of users.

[0005] However, although the above-mentioned structure of the louver tent can achieve a wide opening, so that the louver plates can be folded and retracted to one side, the louver plates need to be folded on one side during the folding process of the louver plates. Compared with ordinary louver tents, it cannot achieve the opening and closing of the louver roof, resulting in a relatively simple overall function.

[0006] Summary of the Invention

[0007] In response to the above problems, the present invention aims to provide an outdoor louver awning with independently flippable opening and closing louvers and telescopic stacking.

The plurality of louvers 110 are driven by the drive seat 114 to complete the spreading or folding; the telescopic transmission mechanism 400 also includes a telescopic drive motor 410 and a transmission shaft 420 driven by the telescopic drive motor 410. The transmission shaft 420 is used to cooperate with the synchronous wheel 430. The transmission shaft 420 is used to drive the synchronous wheel 430 to rotate. The synchronous wheel 430 includes a driving wheel and a driven wheel. The driving wheel and the driven wheel are respectively arranged at both ends of the main beam 210. The transmission belt 440 reciprocates along the driving wheel and the driven wheel. Among them, the telescopic drive motor 410 and the flip drive motor 510 are respectively arranged on both sides of the tent roof 100, adopting independent dual-drive operation to achieve stable transmission control.

[0054] Among them, the telescopic drive motor 410 is preferably a double-headed drive motor, which is used to drive the transmission shaft 420 at both ends to rotate. The other end of the transmission shaft 420 is usually provided with a transmission base 450.

[0056] The present invention optimizes the dual-drive operation to achieve independent flipping, opening and closing and independent side stacking of the louver, thereby improving the performance of the louver tent; the first slide rail groove is used to facilitate the overall sliding of the louver, and in particular, the linkage bar is optimized in design, and the second slide rail groove is built into the linkage bar to form a suspended slide rail structure, so that the linkage bar can synchronously link the louver to flip, and can also serve as a linkage arm moving guide rail component. The use of a guide rope can increase the stability of the movement. Combined with the use of the double-track sliding structure, independent flipping or stacking of the louver can be achieved.

[0057] Example 2

[0058] In combination with Example 1, in combination with Figures 17 to 21, this embodiment discloses an outdoor louver tent with independently flip-opening and stacking blinds, wherein a telescopic transmission mechanism 400 is optimized and designed. In the specific structure, the drive seat 114 is adjacent to the driving wheel side or the driven wheel side, and the louver 110 installed in conjunction with the drive seat 114 is a stacked louver; in this embodiment, the drive seat 114 is preferably arranged on the driving wheel side, and when the louver 110 is in the fully open state, the louver 110 is usually at a 90° angle. The louver body 111 is in an upright state as a whole, and a gap is formed between adjacent louver bodies 111. The telescopic drive motor 410 completes the drive, drives the transmission shaft 420 to transmit, completes the drive of the active wheel, thereby driving the transmission belt 440 to move, and the transmission belt 440 carries the driving seat 114 to move along the driven wheel. As the driving seat 114 moves, the driving seat 114 drives the stacked louvers to move along with the transmission belt 440, and the stacked louvers fit adjacent louvers 110 and complete the stacking and folding of several louvers 110 in sequence.

[0059] In addition, a rope fixing seat 117 is provided on the louver core shaft 112 of several louver plates 100, and stacking ropes 800 are connected between several rope fixing seats 117; the stacking ropes 800 can be used to complete the deployment of several louver plates 110. When several louver plates 110 are gradually retracted to one side as the stacked louver plates are attached, the telescopic drive motor 410 is driven in the reverse direction to drive the transmission shaft 420 to drive, thereby driving the driving wheel, thereby driving the transmission belt 440 to move in the opposite direction, and the transmission belt 440 drives the driving seat 114 to move in the direction of the driving wheel. As the driving seat 114 moves, the driving seat 114 drives the stacked louver plates to move toward the driving wheel along the transmission belt 440, and the stacked louver plates are separated from the adjacent louver plates 110. As the stacking ropes 800 between the adjacent rope fixing seats 117 are tensioned, the louver plates 110 are driven to move toward the driving wheel by pulling the stacking ropes 800, thereby driving the gradual deployment of the entire louver plates 110 in turn.

[0060] Combined with the above structure, the louver 110 can be stacked and folded. In the above structure, in the telescopic and folding structure of the louver 110, the louver 110 needs to pass through a double-track sliding structure. When the louver 110 is in the telescopic state, the linkage bar 530 component is in a stationary state, so that good telescopic stability can be formed, and stacking can be achieved using a double-track double-pulley structure.

[0061] Example 3

[0062] In combination with Example 1 and Figures 6 to 16, this embodiment discloses an outdoor louver tent with blinds that can be flipped open and closed independently and stacked synchronously, wherein a telescopic transmission mechanism 400 is optimized in design. When a number of louvers 110 are driven to flip and open to any angle by the flip transmission mechanism 500, the telescopic transmission mechanism 400 can drive the number of louvers 110 to be stacked. In the specific structure: the drive seat 114 is arranged on any one of the number of louvers 110, and the louver 110 is also provided with a cross-chain unit 710. The cross-chain units 710 between the number of louvers 110 are hinged to each other to form a cross chain 700. The cross-chain unit 710 includes two "X"-shaped linkage plates 711. The intersection of the two linkage plates 711 in the same cross-chain unit 710 is hinged to the louver core shaft 112, and the two linkage plates 711 in two adjacent cross-chain units 710 are correspondingly hinged.

[0063] The optimized design adopts a cross chain 700 structure, which can realize the synchronous extension and retraction of the louver 110. When the louver 110 needs to be folded to one side, the louver 110 can be opened to any angle. There is a gap between adjacent louver 110, which can realize the unilateral retraction of the louver 110. According to the size of the gap specification, the size of the open space after retraction is corresponding to each other; wherein, the preferred opening angle of the louver 110 flipping can be 45 degrees, 60 degrees, and 90 degrees. When the louver 110 is opened, a gap is formed between adjacent louver bodies 11, and the telescopic drive motor 410 completes the drive, drives the transmission shaft 420 to drive, completes the drive of the active wheel, thereby driving the transmission belt 440 to move, and the transmission belt 440 carries the drive seat 114 moves along the driven wheel, and as the driving seat 114 moves, the louver 110 corresponding to the driving seat 114 moves in position. Since several louvers 110 are linked to each other through the cross-chain unit 710, the cross-chain unit 710 at this position is deformed, and its two "X"-shaped linkage plates 711 change, driving the linkage plates 711 in the remaining cross-chain units 710 to change, thereby driving the linkage changes of all louvers 110. As the cross-chain unit 710 is folded and retracted, all louvers 110 are unilaterally retracted. Usually, the linkage arm 115 in the louver 110 located at the outermost end is directly fixed to the linkage bar 530 to facilitate unilateral retraction and positioning.

[0064] In the above structure, in the telescopic and folding structure of the louver, the louver needs to pass through a double-track sliding structure. When the louver is in the telescopic state, the linkage strip component is in a stationary state, thereby forming good telescopic stability. The telescopic stacking is achieved by using a double-track double-pulley structure, which can realize the stacking of the louver in multiple opening and closing states.

[0065] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the invention. Any simple modification, equivalent change or modification made to the above embodiment based on the technical principle of the present invention still falls within the scope of the technical solution of the present invention.
